摘要：

The preparation and properties of luminescent oxygen sensing materials based on two Pt(II)-porphyrin complexes: platinum meso-tetrakis(4-N-methylpyridyl) porphyrin (PtTMPyP4+) and platinum meso-tetrakis(4-N-pyridyl) porphyrin (PtTPyP) assembled in mesoporous silica (MCM-41) are described. The luminescence of Pt(II)-porphyrin/MCM-41 assembly materials can be extremely quenched by molecular oxygen with good sensitivity (I-0/I-100 > 7) and rapid response times (< 1 s) suggest that the Pt(II)-porphyrin/MCM-41 system can be used for developing oxygen sensors. PtTMPyP4+/MCM-41 ( 20 mg g 21) exhibits very high sensitivity ( I-0/I-100 > 50). Even when the concentration of oxygen is 1%, the luminescence intensity of PtTMPyP4+/MCM-41 ( 20 mg g(-1)) can be quenched by 83.33%.
